Scott Pruitt, head of the U.S. Environmental Protection Agency, attended the first few hours of the two-day summit before returning to Washington for a Cabinet meeting, U.S. officials said.

Before his departure, Pruitt's counterparts from Britain, France, Germany, Canada, Japan and Italy expressed their disappointment at President Donald Trump's recent decision to pull the U.S. out of the 2015 Paris Agreement.

The other six countries in the G-7 all agreed at last month's political summit of national leaders in Sicily to work toward making the Paris climate accord effective.

Italy's environment minister, Gian Luca Galletti, who is leading the G-7 environment meeting in Bologna, said that despite the split, dialogue had to continue, including on other environmental issues such as ocean pollution.

Among those pushing hardest to maintain international momentum on combating global warming is Germany, which hosts this year's annual climate summit in November. Environment Minister Barbara Hendricks met Friday with California Gov. Jerry Brown to demonstrate that Germany is prepared to work with individual U.S. states if Trump refuses to be part of the Paris effort any longer.

California is a member of the 'Under 2 Coalition ,' a group of 175 states and cities that aim to help keep global warming below 2 degrees Celsius, a threshold scientists say is necessary to prevent catastrophic climate change.

In a snipe at the Trump administration, Hendricks' ministry on Friday posted a 'fact check' of Trump's speech announcing the U.S. withdrawal from the Paris accord, claiming it contains "blatant fallacies."

The G-7 environment ministers were expected to issue a concluding declaration Monday. Hendricks told reporters that efforts were being made to get all countries — including the U.S. — on board, but that this outcome wasn't certain yet.
